WATER-TEGHT JOINT=-AND METHOD FOR ITS'iRODU'CT'LON.

Application filed April 24, 1923.

My inventi on relates to water-tight joints and a method for their production, and its principal object is to PI'OVlClG a simple, durable and very effective means to prevent leakage of water between the base of a water closet, washstand or other similar fixture, and the floor or other surface upon which it is supported, or around a pipe or other water conduit where it passes through the Another object of the invention is to provide a water-tight joint around a fixture or conduit of the i'iature above referred to, which will effectivelyprevent water from seeping underneath a carpet, linoleum or other floor covering, through the space between the edge of the covering and the part of the fixture or coi'iduit at which it adjoins the floor upon which the coveringis laid.

An embodiment of the invention has been illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which- Figure 1 is a sectional plan view of basal portion of a water closet to which invention is applied;

Figure 2, a section taken on the line 9-2, Figure 1;

Figure 37 an enlarged sectional view of the water-tight joint and the parts to which it is applied; and

Figure at, a perspective view of apiece of the rubber n'iolding strip which is an es sential element of the joint. 7

Referring to the drawings, 5, designates the base of a water closet supported on a floor 6 which has a covering 7 of carpet, linoleum or other suitable substance.

An opening 8 in the base connects with a soil pipe 9 which extends through a hole in the floor.

In order to produce a water-tight joint around the base in accordance with my invention and thereby prevent spilled water from leaking either beneath the base or underneath the floor covering, I cover the joint between the edge of the base and the floor covering by a gasket 10 of putty or other similar plastic filler, and cover the gas ket and the surrounding portion of the floor with a coating 12 of white lead or other pigment. I then place a strip 13 of rubber molding snugly around the coated filler to form a continuous band and fasten the Serial No, 684,286..

strip in 'place by nails or b ads let driven into the floor. ihe joint thus produced may be covered with enamel or other paint to till possible cracks or apertures and to give to the joint a finished appearance in hari'no-ny ith the parts to which it is applied.

The rubber strip 13 which isan essential element of. the joint, is preferably rounded at its upper side to provide a curved surface between the base and the floor covering; its lower side is flat to eveniy engage the floor covering or other surface upon which it is fastened, and its inner side or edge is beveled inwardly to provide a space for the tiller which preferably is made of triangular section with its outer side sloping from the edge of the base to theosurfuce of the floor covering.

It will be evident that the joint thus pro duced covers the space between the edge of the floor covering and the base and thoroughly closes it against the passage of water, and it is to be understood that the joint may be formed in like manner around water conduits where they adjoin or 3885 through an opening in a floor or other surface or around the base of a washstand or other fixture, and that while it is particularly adapted to cover the space between a floor covering and a fixture, it is also of value if applied directly to the surface of a floor where no covering is provided.

Variations in the materials used in the production of the joint and in the form and arrangement of the constituent elements of the same may be resorted to within the spirit of my invention as defined in the following claims.

What I claim and desire to secure by Letters Patent is:

1. A joint of the character describedcomprising in. combination with the foot of a water fixture, having a surface extending upwardly from the floor, a floor covering terminating adjacent said surface, in slightly spaced relation thereto, a plastic filler covering the space between the covering and the foot of the fixture in engagement with said surface of the foot, and a flexible packing strip secured to the floor upon said covering and bearing at its upper edge against the foot of the fixture above the plastic filler, the inner face of the strip opposite said surface being inclined away from the :UI'fzlC": from its -=ziid upper edge dawnwr'dly to compress he filler between fhe p and the foot.

joint of the ehaiiictei described com pining: iii mmbimitinn with Hie foot of a ivziiei' Fixiuie and :1 suii'ziee upon which it is siqiipoi'Led, a strip nailed upon the surface iii-mind the foot of the fixture, the

inner face of the strip being inclined. i'i'mii its upper edge which engages tLe foot of the 10 fixture, away from the same to provide recess of a wedge-shaped Cross section and a plastic filler iii the recess.

In testimony whereof I. irn'e :ifiixed my signature.
